Risk Disclosure

Futures, foreign currency and options trading contains substantial risk and is not for every investor. An investor could potentially lose all or more than the initial investment. Risk capital is money that can be lost without jeopardizing ones financial security or lifestyle. Only risk capital should be used for trading and only those with sufficient risk capital should consider trading. Past performance is not necessarily indicative of future results.

Bar Length Solver


The Bar Length solver is used to detect the bar’s total range (vertical length) from low to high. Similar to the Range indicator. An output value is given in both directions.

Output Modifiers

Output Modifiers

This section provides quick access to commonly used output modifiers.
Please note:   The buttons only modify the individual instance of the selected node(s) on a Logic Board.   Thus, the buttons are only visible when a node is selected on the Logic Board.  The buttons are not available when a solver is selected in the Solvers panel, because the original solver's output can not be globally modified.
This behavior is consistent with adding a function node afterwards, so that the original solver's output remains unmodified elsewhere in the system.  It is similar to having an SMA(50) on several charts.  Changing the plot color on one chart does not modify the plot color on the other charts.



Global Properties

Global Properties

These setting apply to all instances of the selected solver.  Changing a setting in one of the instances changes the setting in all instances.  If you only want to change one of the solvers, but not the others, you must make a copy of the solver.  The copy will be a different solver, and a number will be added at the end of the name to differentiate it from the original.

Behavior

This option determines which outputs are calculated.  Effectively turning off either the Long or Short output.

Options tab

Options tab



This tab contains extra secondary settings common to all nodes.

This section is used to modify the node's final output value.  It is only useful for designing fuzzy logic systems, or a fuzzy logic section of a system.
Please note:   The Weight controls only modify the individual instance of the selected node(s) on a Logic Board.   Thus, the Weight controls are only visible when a node is selected on the Logic Board.  The controls are not available when a solver is selected in the Solvers panel, because the original solver's output can not be globally modified.
This behavior is different than BloodHound 1.0.  In BH 1.0, the Weight controls modified the nodes output globally (every instance).  This change in BH 2.0 adds more system design granularity.

Multiply Output:   This takes the internal values (the Long and Short values determined via the Properties tab » Output Rules section) and multiplies them by this value.  Note: the final output will not exceed a value of 1, as described in the Slider control below.

Slider control:  The slider constrains the final output to a value of 0 to 1.  The left side of the slider sets a minimum value that is output regardless if the solver condition is true or not.  The right side sets a maximum value that is output.  The output is capped.
e.g.  Three indicator conditions are being checked, and thus three solvers are created.  Only two out of the three indicator conditions are needed.  An Additive logic node is used to add the solver's outputs together.  Just two out of the three solvers need to add up to a value of 1.  Therefore, the right slider (max output value) for all three solvers is set to 0.5.  When two indicator/solver conditions are found, thus the outputs = 0.5, then the calculation, in the Additive node, is 0.5 + 0.5 + 0 = 1.  A value of 1 means the two out of three condition is true.

Hedge Operation: This applies a mathematical formula to the internal value.
None:  No modification is applied.
Very (square output):  A squaring formula is applied.  Output  =  value .
Somewhat (square root output):  A square root formula is applied.  Output  =  √value .


Description

Description

This text area provides a place to write a full description of what the node is doing, used for, or what ever you want.
Note:   The Description is global to all instances of the node.  It is not applied individually to each instance as the Weight controls are.

This tab displays the documentation page (from this web site) of the selected node.
Please note:  NinjaTrader v8.0.26.0 or newer is required for the built in web viewer to work, and thus the documentation to be displayed.




Video Tutorial

This video shows BloodHound v1, however the settings and usage are the same.


Examples

The screenshots below show BloodHound v1, however the settings and usage are still the same.

Example 1: The Basics

This demonstrates the basic function of the Bar Length solver by testing for a bar range (High – Low) of 10 ticks or greater.  A simultaneous output of 1 & -1 indicates a bar length is 10 ticks or more.

  • Add the Bar Length Solver.
  • Set the Max to 10 Ticks.

As seen in the chart, an output of 1 & -1 occurs on bars 10 ticks or more.



Example 2: News Volatility

In this next example let’s look for a possible news event affecting price volatility.  This could be done by searching for a bar range that exceeds the ATR by a certain factor.  This example will use 400 percent.  And, lets give the market 15 minutes or 5 bars afterwards to settle down.

  • Add the Bar Length Solver.
  • Set the Mode to Largest.  This will track bars with the largest range.
  • Set the Period to 6.  The “signal” bar is 1, plus 5 more bars afterwards.
  • Set the Max to 4 ATRs.

As seen in the chart, a racing stripe occurs when the bar range is 4 times or greater than the ATR.  1.778 x 4 = 7.152, rounded to the nearest tick size = 7.2pts.  Note that several bars after the signal still had high ranges, although the bar did not quite meet the racing stripe threshold, which, for these examples, is set to 0.8.
